I will be reviewing these rums in the near future on my website. The Cognac Cask Rum is not available in the UK yet but will be later according to my contact. According to Papa Jules you can get the white and gold rums from Venus at a significantly cheaper price. I'm not sure if it was http://www.venusandco.com he was refering to.

I had a chance to taste this rum last night at the Tonga Hut, King Kukulele brought two bottles there for us to sample, I preferred the dark one. It was very good. Would be nice to be able to purchase this rum here in the States.

The Gold Rum has been reviewed, it is a pretty nice rum but I'd probably wait for the prices to drop before rushing off to buy one from Selfridges or perhaps it is better to wait till September when they will be more widely available. I've also included some cocktail making in this review (with pics!).

Tommy Bahama and Mahiki rums are not the same, but they do come from the same distillery & blender. I tried both in May when I was visiting Richard Seale and the Mahiki has a higher percentage of their pot distillate in the blend then the Tommy Bahama.
